LAUNDRY MANGLES Fi1ed Dec. 5, 1963 4 sheets-Sheet 8 ---I-I-I- United StateS Patent This invention felates td i-InpTovements in laundry mangles. Laundry mangles With two ol three rollefs, 0ne of Vvhich rnay be Tessed by Spring f0rce iT}t0 an operative position against one or two lot0r driven rollers and then be Inoved into an in0perative position by manuauy operated nleans, Suer from the drawback that considerable f0rce is Tequired to overcome the spring 1)ressufe against the a(1j11stable 10ller vvhen moving the latte1- into its in 0pefative position lhis invention has for its object the elixnination of the above drawback, thus facilitaing operation of the I1angle' '1"he improved laundry mangle acc0rding to the I)eSent invention iS mainly characterized in that it c0mprises means that are combined With the rolleT system of the nlangle and adapted 0 be brought, through Inanual actuation 0f one Of the Enean8, into direct or indirect c0 0peration With the motol' driven T01ler of the mangle, and With one 0f its driven rollers espectively, in ordef to eect a Inoven1ent of the adjuSable T01ler int0 in 0perative position, and to Stop the motor aut0matical1y at the same time A Spring combined With the said means and With the adju3table r01ler is adapted to restofe Said adjustable r01lel aut0fhatica11y t0 an 01)erative p0sition When the mot01 iS Started.

The invention wm 'appear moTe clearly from the fol- 10Wing detailed description When taken in conjunction With he accompanying drawings Showing by Way 0f exan ple, the preferred enbodiments of the inventive con- 0el't,

In the drawings:

FIGURE 1 Shows dia ranmatica1l an embodiment of the invention n combination vvith a laundry Inangle with a roner System comprising two T01lers hat are mounted in stationary beaings and driven by an electric mptor, and a roller Which is vadjuStb1e relative to these T0Hefs and can be 1)Tessed aga inst them by Spring force FIGURE lz is similar to FIG 1 but Shows the device in its operative 1)0Sition.

Fastened to the Shaft of the belt puney 8 is a Sprocket wheel 10 Which transmits the motor power by means of a chain ll t0 the wheel 5 and the Toller 2. A Sprocket wheel lz is fastened to the Shaft 16 0f the roller 3, and a siln'ila1 Sprocket Wheel 14 is Xed to the Shaft 13 0f the Toller l. The Sprocket wheels 5 and 14 have the same number of teeth Or c0gs and a driving chain 15 placed on heSe Whee'1s transInits driving p0wer from the mot01 driven Tolle1 z to the roller l The ends of the Shaft l of the rouer 3 are mounted in bearings 17 Which are displaceable in the lateral direc tion of the rollers 1 and z Shafts 4 and 13 0f rollers l and 2 respectively, ale mounted in bearing brackets 18 Which are fa'stened t0 the Inangle casing, for instance t0 inner end walls pOVided in the cas'ing, The brackets 18 are provided With recesses 19 forming )araTlel, Op posed edges on vvhich bearings 17 'are Slidably supported The bearings 17 are provided vvith grooves 20 Which^receive the edges of the recesses l in the brackets 18. The Tecess 1 0f each bracket 18 foTms a certain angle vvith an in1aginafy diametrica1 connecting line extending between T01lers 1 and z.

Rotataby mounted in the brackets 18 is 'a Shaft 21 Which extends paa11el ol appr0xifnately parallel to the r01lefs l and z.
